Answer 1

8. Let the Total Income be rs x then

His expenses are 20% and 60% on House rent and House Hold Expenses from his Total Income  

And he saves Rs 2520

House  rent  Expense, 20/100*x  = Rs 20x /100

House Hold Expense, 60/100*x  = Rs 60x/ 100

Then His Total Income is  Total Expenses = Savings

20x /100 + 60x/ 100 = 2520

20x+60x/100 = 2520

80x = 252000

x = 252000/80

x =  3150

His Total Income for a month  is  Rs 3150

Only one sum ok I don't have sufficient time

Otherwise I would have solved all of these
